• 10.1-3.93 is so easy but a little bit hard
• Note that 3.93 is only 0.07 less than 4. So we can subtract 4 from 10.1 to get 6.1 (or 6.10), then add back 0.07 to get a final answer of 6.17.

• ok, so the first thing i would do is line it up.
22.0 I would add the zero on top of the seven
-10.7 21-10=11 and ten -7 is 3
Hope that helps
